STEE RING DEVICE FOR TRACTION-ENGINES.

SPECIFICATION forming part of Letters Patent No. 567,696, datedSeptember 15, 1896.

Application filed August 2 9 18 95.

To all whom it may concern/.- I

Be it known that I, GEORGE CLAYTON STE- VENSON, a citizen of the UnitedStates, and a resident of Carlos City, in the county of Randolph andState of Indiana, have invented certain new and useful Improvements inStea1n- Guides for Traotion-Engines, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof, in which similar letters of reference indicatecorresponding parts.

This invention relates to steam-guides for traction-engine's, and theobject thereof is to provide an improved gear mechanism con nected withthe forward truck or axle of a traction-engine, by means of which theengine may be guided; and with this and other objects in view theinvention consists of the construction, combination, and arrangement ofparts hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which- Figure 1 is aside elevation of a tractionengine provided with my improvement, andFigs. 2, 3, and 4 represent details of the construction.

In the practice of my invention I mount upon the boiler A of atraction-engine a gearring B, which is composed of two semicircularsections united 011 the opposite sides, as shown at C, and also mountedin bearings D, of any preferred form and construction, and secured tothe boiler in any desired manner. The ring B is free to revolve on theboiler A, and is angular in crosssection, and the forward upper portionthereof is beveled and provided with gear-teeth on its upper and lowersides, as clearly shown in Fig. 1.

Connected with the forward axle E,bymeans of arms F, is a segmental gearG, also beveled and adapted to engage with the under side of thegear-wheel B, as clearly shown in Fig. 1, and said segmental gear isheld in connection with the gear-wheel B by means of a bearing orsupport H.

Pivotally connected with.the upper side of the boiler is a doublesegmental gear K, the rear end of which is beveled and provided withgear-teeth adapted to mesh with the up per teeth of the ring B, asclearly shown in Fig, 1, and said segmental gear and the ring Serial No.560,901. (No model.)

B are held in connection by means of a bear ing L, secured to the boilerin any desired manner, and the forward end of the double segmental gearK is adapted to engage and operate a worm-gear M on a shaft m, which issecured transversely of the boiler by means of bearings N, said bearingsand said shaft being located near the forward end of the boiler. Theouter end of said shaft is provided with a beveled gear-wheel 0, adaptedto engage with a corresponding beveled gearwheel P, mounted on averticalshaft R, which is mounted in bearings r, and the lower end of said shaftR is provided with a beveled gear-wheel S, adapted to engage with andoperate corresponding beveled gear-wheels T, mounted on the shaft U, tothe outer end of which is secured a crank-wheel WV, all of which isclearly shown in Figs. 1, 2, and l.

The gear-wheels T are mounted on or secured to a sleeve T, which isadapted to slide back and forth on the shaft U, and said sleeve isprovided with a collar T by means of which is formed an annular grooveT, which is adapted to receive a yoke T provided with an arm which ispivotally connected with a lever T in and by means of which said sleevemay be moved back and forth, as will be readily understood. In thenormal position of the parts, the gear-wheel S is not engaged witheither of the gear-wheels T, but said gearwheel S may be thrown intoconnection with the wheels T by means of the lever T pivoted to the lugupon a boiler, and the direc tion of the machine will depend upon thegear-wheels T, with which the gear-wheel S is placed in connection, oneof said wheels T being designed to turn the forward axle in onedirection and the other to turn it in the other direction, as will bereadily understood.

The operation will be apparent from the foregoing description, whentaken in connec tion with the accompanying drawings. The shaft Uisrevolved by means ofa belt or other device connected with the propellingmechanism, (not shown,) and the gear-wheel S is thrown into connectionwith one or the other of the wheels T, as hereinbefore described, thewheel T with which the connection is made depending upon the coursewhich it is desired that the engine shall take, the double segmentalgear K, the ring B, and the segmental gear G, connected with the forwardaxle, being operated by the shaft m and its connected gears when thegear-Wheel S is connected with one of the gear-wheels T, as will also bereadily understood.

It is evident that changes'in the form, 0011- struction, and combinationof the various parts of my improved steam-guide for traction-engines maybe made without departing from the spirit of my invention or sacrificingits advantages; and I therefore reserve the right to make suchalterations therein as fairly come within the scope of the invention.

Having fully described my invention, I claim and desire to secure byLetters Patent The combination with a traction-engine provided with arevoluble beveled gear-rin g encircling the boilers front end, of asegmental beveled gear arranged to mesh with the said gearing below theboiler; a double segmental gear arranged to mesh one segment with thegearing above the boiler, and to mesh the other segment with a worm-gearthat is fixed transversely on the boiler near the front thereof abeveled gear-wheel fixed on the outer end of said worm-shaft andengaging with a corresponding gear mounted on a vertical shaft at theside of the boiler on Whose lower end is still another gear-wheelengaging with a corresponding train-wheel mounted on a sliding sleeveprovided with a collar having an annular groove, on a transverse shaftto whose outer end is secured a belt-pulley; a yoke engaging in thegroove of the said collar and having its arm pivotally connected with alever by means. of which the sleeve may be moved back and forth fordirecting through its connections, the course of the engine, allconstructed and arranged substantially as herein shown and described.

In testimony that I claim the foreging as my invention I have signed myname, in presence of two witnesses, this 19th day of August, 1895.

GEORGE CLAYTON STEVENSON.
